Hair analysis serves as an influential method for detecting the use of drugs and alcohol. By embedding biomarkers into the expanding fibers of hair strands, hair retains a comprehensive historical record of substance use. When samples are taken near the scalp, hair can reveal drug and alcohol use within an estimated detection period of three months. Hair samples are straightforward to gather, difficult to tamper with, and convenient for transport.
A 1.5-inch cluster of roughly 200 hair strands (equivalent in size to a #2 pencil) positioned nearest to the scalp equates to 100mg of hair, which is the optimal amount for both screening and verification. For tests involving EtG, additional panels, or more than 10 panels, 150mg of the sample is advised. Measuring the sample with a jeweler’s scale is suggested. In the absence of scalp hair, an equal portion of body hair can be gathered. By head hair, we mean solely scalp hair, while body hair pertains to all other hair categories (e.g., facial, axillary).
Process Overview
The primary stages in processing a laboratory drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a test sample into a lab’s database. This process ensures that the sample was securely sealed and transported, a random LAN (Laboratory Accessioning Number) is assigned, and any remaining data entry not available through electronic tracking is completed.
Screening provides an initial brief examination for controlled substances. Although Screening is an economical method for excluding drug presence in most cases, positive screenings must undergo confirmation to be legally viable. Any samples that yield a presumptive positive in Screening necessitate secondary validation.
Should a sample indicate a presumptive positive at the Screening phase, additional hair is drawn from the initial collection and readied for Extraction. At this point, drugs are isolated from hair at substantially diminished concentrations compared to other techniques (like urine or oral fluids), illustrating why hair drug testing is among the more challenging methods.
Positive Screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positives are cleansed as necessary. The complete process, from Accessioning to Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair criteria and meets ISO/IEC 17025 accreditation standards.
